Abstract

A heat pump system for cooling (refrigeration) or heating is provided by combination of natural media such as ammonia and CO2. The heat pump system (1) combines an ammonia cycle (2) and a CO2 cycle (3), and the CO2 medium in the CO2 cycle (3) is circulated, by natural circulation due to difference of fluid heads of CO2 medium in the cycle without incorporating a compressor, and by partial heating or cooling of the cycle. The structural elements of ammonia cycle (2) are placed away from the devices for the desired refrigeration and heating. <IMAGE>
